Emax Es08ma Ii Datasheet

For those integrating the servo into a DIY project, here is a minimal Arduino example using the built-in Servo library.

#include <Servo.h>
Servo myServo;
const int servoPin = 9; // PWM-capable pin
void setup() 
myServo.attach(servoPin, 1000, 2000); // min, max pulse width
myServo.write(90); // center position
delay(1000);

void loop() 
// Sweep from 0 to 180 degrees
for (int angle = 0; angle <= 180; angle++) 
myServo.write(angle);
delay(15); // Wait for servo to reach position (speed: 0.10 sec/60° = ~10ms per 10°)
for (int angle = 180; angle >= 0; angle--) 
myServo.write(angle);
delay(15);

Important: The ES08MA II is analog, so do not use a refresh rate higher than 70Hz. The Arduino Servo library defaults to 50Hz, which is perfect.

While the datasheet provides typical values, real-world performance depends on load and temperature. Emax Es08ma Ii Datasheet

Ultimate Guide to the Emax ES08MA II: More Than Just a Budget Servo

If you’ve spent any time in the RC or micro-robotics world, you’ve likely encountered the Emax ES08MA II

. Often hailed as the "king of micro servos," it strikes a rare balance between affordability and durability. Whether you're upgrading an Axial SCX24 For those integrating the servo into a DIY

, building a custom 3D-printed robot, or looking for a reliable fixed-wing surface control, this guide breaks down the essential datasheet specs and why it matters for your build. 🛠 Emax ES08MA II Technical Specifications

At its core, the ES08MA II is a 12g analog micro servo with a full metal gear train. Here is the data you need to know: Specification Operating Voltage 4.8V – 6.0V Stall Torque (4.8V) 1.6 kgf·cm (21.0 oz·in) Stall Torque (6.0V) 2.0 kgf·cm (28.0 oz·in) Operating Speed (4.8V) 0.12 sec / 60° (no load) Operating Speed (6.0V) 0.10 sec / 60° (no load) Dimensions 23 x 11.5 x 24 mm Gear Material Signal Type Spline Count 15T (Standard Mini) 🚀 Key Performance Highlights 1. Full Metal Gear Train

Unlike the plastic gears found in standard 9g servos (like the SG90), the Emax ES08MA II

utilizes a robust metal gear setup. This is a game-changer for high-stress applications—like steering a heavy micro crawler—where plastic gears would typically strip. 2. Compact Powerhouse

Weighing only 12g, this servo delivers up to 2.0 kg of torque at 6V. For context, that’s enough power to handle many 1/24 scale vehicles and light 1/18 scale planes without adding significant bulk. 3. Reliability & Compatibility

The ES08MA II is widely compatible with most receivers (FUT/JR plugs). It is a "standard" upgrade for the Axial SCX24 community, frequently paired with the INJORA Aluminum Servo Mount for a rock-solid steering setup. ⚠️ Pro-Tips for Your Build Mind the Voltage: void loop() // Sweep from 0 to 180

While it performs best at 6V, ensure your BEC (Battery Eliminator Circuit) can handle the current. Some users suggest checking for stall current draw to avoid "brownouts" on power-hungry systems. Analog vs. Digital: Keep in mind that this is an

servo. While highly reliable, digital servos often offer more precision and holding power (albeit at a higher cost). The Spline: This servo uses a 15T spline

. If you are buying aftermarket servo horns or mounts, double-check that they are compatible with this specific tooth count. Final Verdict

The Emax ES08MA II remains one of the best value-for-money upgrades in the hobby space. If you need a small, metal-geared servo that won't break the bank, this is the industry standard. high-voltage (HV)

The Emax ES08MA II is a high-torque, 12g mini analog servo known for its durability due to an all-metal gear train . It is widely used in RC planes, 450-class helicopters, and small robotics like the SCX24 crawler . Core Performance Datasheet

The ES08MA II operates within a standard voltage range, with performance scaling based on the input power: Specification Stall Torque 1.6 kgf·cm (21.0 oz·in) 2.0 kgf·cm (28.0 oz·in) Operating Speed 0.12 sec / 60° 0.10 sec / 60° Running Current Stall Current Data sources: Physical & Electrical Attributes

| Voltage | Speed | Unit | | :--- | :--- | :--- | | 4.8V | 0.12 sec/60° | seconds | | 6.0V | 0.10 sec/60° | seconds |

Interpretation: With a speed of 0.10 seconds at 6V, this is considered a medium-fast servo. It is not a race servo (like a 0.06 sec unit), but it is perfectly adequate for flight control surfaces on a 1-meter wingspan plane or dynamic leg movement in a small robot.
